Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective equipment technology, specifically to a safety back armor for mining. Background Technology
[0002] A safety backplate for mining is a back protection device specifically designed for underground operations. It is mainly used to protect the spine, waist, and other critical parts of the human body from external forces such as falling rocks and collisions.
[0003] Chinese patent CN208096067U discloses a safety backplate for mining. Its structure includes a shoulder strap and several protective plates. The protective plates are hinged from top to bottom. The upper end of the shoulder strap connects to the first protective plate, and the lower end connects to the last protective plate. The hinges are installed inside the protective plates, with a rotation angle of 0-180 degrees. A transverse groove is provided on the outer wall of the protective plate, within which a reflector is slidably installed. The reflector has a reflective coating on its outer side. This invention uses hinges to connect the protective plates, and the hinges can only rotate inwards. When a rock falls on the backplate, adjacent hinged protective plates cannot rotate outwards, forming a flat surface, effectively reducing the risk of injury from falling rocks. The reflectors on the outer side of the protective plates are detachable via the grooves, making replacement convenient. In situations of poor visibility, such as at night, with low visibility, or due to fatigue, the reflectors increase the user's visibility distance, enhancing safety.
[0004] However, the above-mentioned existing technology has the following shortcomings: During use, although when a rock falls on multiple sets of protective plates, the multiple sets of protective plates cannot be flipped to form a flat surface for protection due to the action of the hinge, when a rock falls on the hinge between the protective plates, the impact force will cause the protective plates to be forcibly flipped. The edge of the flipped protective plate may compress the soft tissue on the back due to inertia, forming abrasions or hematomas, which will aggravate the degree of local damage. Summary of the Invention
[0005] The purpose of this utility model is to solve the problem that, during use, although multiple sets of protective plates cannot be flipped to form a flat surface for protection when a rock falls and hits them, the impact force causes the protective plates to be forcibly flipped when the rock falls and hits the hinge between the protective plates. The edges of the flipped protective plates may compress the soft tissue on the back due to inertia, forming abrasions or hematomas, which aggravates the degree of local damage. This utility model provides a safety back armor for mining.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety back armor for mining, comprising: a protective component for protecting the user's spine, wherein the protective component is provided with a reinforcement component for protecting the flipped area, and a wearing strap is fixedly connected to the protective component;
[0007] The protective component includes multiple sets of protective plates evenly distributed in a 1-shape, and the multiple sets of protective plates are fixedly connected by a hinge.
[0008] The reinforcement component includes a connecting block fixedly connected to the protective plate. A rotating shaft is connected through the side end of the connecting block and is rotatably connected to the connecting block. A reinforcing plate is connected through one end of the rotating shaft and is rotatably connected to the rotating shaft. Each set of protective plates is provided with a connecting block, a rotating shaft and a reinforcing plate, and two hinges are fixedly connected to the reinforcing plates of two adjacent sets of protective plates.
[0009] As a further embodiment of this utility model: the connecting blocks are provided in multiple sets, and each set of reinforcing plates is rotatably connected to three sets of connecting blocks through a rotating shaft. Each set of reinforcing plates consists of a set of horizontal plates and two sets of vertical plates arranged in a double cross shape, and the three sets of connecting blocks and the two sets of vertical plates are staggered.
[0010] As a further embodiment of this utility model: the second hinge is disposed at the connection between two adjacent sets of protective plates, and the first hinge in the protective component and the second hinge in the reinforcing component are disposed in opposite directions.
[0011] As a further improvement of this utility model: the connecting surfaces of the two adjacent sets of protective plates in the protective component and the two sets of reinforcing plates in the reinforcing component are bonded together, so that it can only rotate towards the surface where the hinge is located. When rotating to the other side, the bonded connecting surfaces abut against each other, preventing it from rotating.
[0012] As a further embodiment of this utility model: among the multiple sets of protective plates distributed in a 1-shape in the protective component, the uppermost set of protective plates is fixedly connected to a connecting ear one, and the lowermost set of protective plates is fixedly connected to a connecting ear two, and the wearing strap is fixedly connected to the connecting ear one and the connecting ear two respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes a fixed connection between the connecting block and the protective plate, along with a linkage design of the rotating shaft. This allows the reinforcing plate to move synchronously with the protective plate, ensuring that the reinforcing plate always moves in tandem with the protective plate when the user moves their back. This prevents gaps caused by asynchronous component movement. The double-cross structure of the reinforcing plate and the three sets of connecting blocks are staggered, significantly enhancing structural stability and dispersing impact force in multiple directions, thus improving impact resistance. The second hinge is positioned opposite to the first hinge of the protective component, working in conjunction with the connecting surface of adjacent reinforcing plates. This ensures the reinforcing component can bend flexibly with body movement and can quickly lock in place when impacted by falling rocks, forming a complete plane that precisely covers the weak point of the hinge in the protective component. This compensates for blind spots in the connection of a single protective plate. The overall protective structure, formed in conjunction with the continuous plane of the protective component, effectively prevents impact force from concentrating at gaps, thus significantly improving the impact resistance of the back-turning area.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0023] Reference Figure 1 In this embodiment of the utility model, the safety back armor for mining includes: a protective component 1 for protecting the user's spine, a reinforcing component 2 for protecting the flipped area, and a wearing strap 3 fixedly connected to the protective component 1.
[0024] Reference Figure 4 The protective component 1 includes multiple sets of protective plates 11 evenly distributed in a 1-shape. The multiple sets of protective plates 11 are fixedly connected by hinge 12. The uppermost set of protective plates 11 in the 1-shape distribution of the protective component 1 is fixedly connected to a connecting ear 13, and the lowermost set of protective plates 11 is fixedly connected to a connecting ear 24. The wearing strap 3 is fixedly connected to the connecting ear 13 and the connecting ear 24 respectively.
[0025] The above solution is adopted: the protective plate 11 with the 1-shaped distribution can completely cover the spine area, the hinge 12 allows the protective plate 11 to bend flexibly with the back movement, and the connecting ear is connected to the wearing strap 3 to distribute the force of the protective component 1 to the strap to avoid local pressure, while ensuring that the protective plate 11 is always located on the back during the activity, ensuring accurate protective position.
[0026] Reference Figure 5The reinforcement component 2 includes a connecting block 21 fixedly connected to the protective plate 11. A rotating shaft 22 is connected through the side end of the connecting block 21 and is rotatably connected to the connecting block 21. A reinforcing plate 23 is connected through one end of the rotating shaft 22 and is rotatably connected to the rotating shaft 22. Each set of protective plates 11 is provided with a connecting block 21, a rotating shaft 22 and a reinforcing plate 23, and hinges 24 are fixedly connected to the reinforcing plates 23 of two adjacent sets of protective plates 11.
[0027] The above scheme is adopted: a linkage structure is formed by connecting block 21, rotating shaft 22 and reinforcing plate 23. Connecting block 21 transmits the movement of protective plate 11 to rotating shaft 22. Rotating shaft 22 drives reinforcing plate 23 to move synchronously. Hinge 24 enables the reinforcing plate 23 of adjacent protective plate 11 to rotate in coordination, ensuring that the reinforcing part 2 can respond synchronously with the movement of protective part 1 and always form effective protection for the overturned part.
[0028] Reference Figures 2 to 5 Multiple sets of connecting blocks 21 are provided. Each set of reinforcing plates 23 is rotatably connected to three sets of connecting blocks 21 via a rotating shaft 22. Each set of reinforcing plates 23 consists of a set of horizontal plates and two sets of vertical plates arranged in a double cross. The three sets of connecting blocks 21 and the two sets of vertical plates are staggered. The second hinge 24 is set at the connection of two adjacent sets of protective plates 11. The first hinge 12 in the protective component 1 and the second hinge 24 in the reinforcing component 2 are set in opposite directions. The connecting surfaces of the two adjacent sets of protective plates 11 in the protective component 1 and the two sets of reinforcing plates 23 in the reinforcing component 2 are attached to each other, so that they can only rotate towards the surface where the hinge is located. When rotating to the other side, the attached connecting surfaces abut against each other, so that they cannot rotate.
[0029] The above solution is adopted: the staggered design of multiple sets of connecting blocks 21 and double cross reinforcing plates 23 enhances the structural stability and stress distribution capability of the reinforcing plates 23. The reverse setting of the hinges and the abutment restriction of the connecting surface not only ensure the flexibility of the equipment with body movement, but also can quickly lock into a rigid plane when impacted, avoiding the failure of protection due to excessive flipping, and greatly improving the reliability of impact protection.
[0030] The working principle of this utility model is as follows: When the user moves their back, the adjacent protective plates 11 in the protective component 1 rotate around the hinge 12 towards the surface where the hinge is located. Since the protective plate 11 is fixedly connected to the connecting block 21, its rotation drives the rotating shaft 22 to move synchronously through the connecting block 21, so that the two sets of hinged reinforcing plates 23 are subjected to corresponding forces, thereby driving the reinforcing plates 23 that are rotatably connected to the rotating shaft 22 to move synchronously. At this time, the reinforcing plates 23 of the two adjacent sets of protective plates 11 rotate around the hinge 24 towards the surface where the hinge is located. When a falling stone hits, the impact force causes... The adjacent protective plates 11 of protective component 1 tend to rotate towards the side other than hinge 12. Because the adjacent connecting surfaces of protective component 1 are in contact and cannot rotate, multiple sets of protective plates 11 quickly form a continuous plane. At the same time, the adjacent reinforcing plates 23 of reinforcing component 2 tend to rotate towards the side other than hinge 24 under impact force. Similarly, because the connecting surfaces are in contact and cannot rotate, the reinforcing plates 23 connected by hinge 24 form a plane and cover the area where hinge 12 is located. Together with the continuous plane of protective component 1, they form an overall planar protective structure, thereby completing the protection against falling rocks. Comprehensive impact protection; through the fixed connection between the connecting block 21 and the protective plate 11 and the linkage design of the rotating shaft 22, the reinforcing plate 23 can move synchronously with the movement of the protective plate 11, ensuring that the reinforcing plate 23 always moves in tandem with the protective plate 11 when the user moves their back, avoiding protective gaps caused by asynchronous movement of components. The double cross structure of the reinforcing plate 23 and the three sets of connecting blocks 21 are staggered, greatly enhancing its structural stability and dispersing the impact force in multiple directions, improving impact resistance. Hinge 24 and hinge 1 of the protective component 1 are also included. 2. The reverse setting, combined with the connecting surface of the adjacent reinforcing plate 23, ensures that the reinforcing part 2 can bend flexibly with body movement, and can also be quickly locked by the connecting surface when a rock falls, so that the reinforcing plate 23 forms a complete plane, accurately covering the weak point of the hinge 12 in the protective part 1, making up for the blind spot of the connection part of the single protective plate 11. The overall protective structure formed by working together with the continuous plane of the protective part 1 effectively avoids the protection failure caused by the impact force being concentrated at the gap, and significantly improves the impact resistance safety of the back flipped part.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
